“There are many ethnicities crammed into a fairly small area here,” writes John in Singapore, “and sometimes there are…frictions. The red bin referred to in the note (at the bottom of the photo there) is an incinerator for firing up offerings to various deities/dearly departed by Chinese Buddhists. They are all over the place here in Chinatown, and everybody knows what they’re for.”

Without a doubt, John says, “The Korean gentleman using it as an ashtray is provoking his neighbors deliberately.” How…how…what’s the word I’m looking for here?

Our anonymous submitter was mildly amused when he noticed this little hypothetical how-to pop up in his Facebook feed. But the real kicker, he realized, is that the one person tagged in the note happens to be (ouch) the notewriter’s current roommate.

Adds our submitter: “To my surprise, the girl never commented on it, but I’m sure she got the message — she was called out!”

“One of my coworkers — normally a calm, even-keeled woman — sits near the door of the office,” writes Ali in Minnesota. “When others come in at night to write reports or look up info, they apparently destroy her desk in the matter of minutes. After a series of coffee cups and chair-lowerings, up went this note. Everyone in the office found it so funny they started adding snarling animals to the note. Ferocious!”

While I can understand this woman’s frustration, one thing I’ll never be able to understand is the logic behind highlighting an entire (caps-locked!) message.

I’ll admit, my first thought upon reading this note — found in the hallways of an American high school — was something along the lines of “Argh, kids today, with their chatspeak!” Can we all agree that adolescent girls are probably the most passive-aggressive creatures on earth?

Alec in Houston found this little work of art on his desk, he says, “after I went out for lunch and didn’t do the dishes like they had asked.” With gritted teeth, he goes on: “They have ‘too much work’ and I have ‘none’ so I might as well wash them!”

Writes Tim in Berkeley: “Although this note is over 17 years old, I think it’s still worth submitting, at the very least as an example of notes from a bygone era. I received this note from the apartment manager when I was a senior at Rice University, living in an off-campus apartment. Admittedly, I wasn’t the cleanest tenant — but what 20-year-old college kid living alone in a studio apartment is?”

Adds Tim: “The really sad thing was that I had cleaned my apartment before this note — she should have seen the place before!”

Writes Kerry in Brooklyn: “I just moved into a new apartment, and they don’t have secured outside parking for bikes. My place is NYC-sized, so naturally I decided to lock one of my bikes to the banister right outside my door. Apparently that’s a big no-no in the building.”

Meanwhile, Melanie in Newport, Rhode Island spotted this on the lawn of the Salvation Army in her neighborhood, adding “I, for one, certainly applaud whomever had the baguettes to do such a thing.”

Writes our anonymous submitter: “Unable to visit my mother last year for Mother’s Day, my partner and I sent her a box of chocolate truffles and an antique brooch. This is her ‘thank you’ note (which is really more like a ‘fuck you’ note).”

The final “fuck you,” of course, is the nearly indecipherable handwriting. Here’s the transcription:

Looked forward to seeing you on Mother’s day. In Lieu of such optimism I enjoyed the truffles as fattening as they are + the pin is very attractive. Thanks. Love, Mom

"The thing that drives me bonkers at work is to open up the trash can drawer and see a cup half-full of water that was carefully placed into the trash can so it doesn't spill--in a trash can an arm's length away from the kitchen sink!

99% of the people in my office are college graduates, probably toward the top of their class. But some without enough common sense to pour the water in the sink before putting the cup into the trash can.
